Earlier,
Luke Palmer asked for a clear definition of when math should use floating
points and when it should be integer-based. In response, Darren Duncan
highlighted a recent #perl6 discussion
on the topic. He proposed distinct operators to allow users to explicitly
choose the math mode. Jonathan Lang mentioned that in the one other
instance where there were type-specific versions of a common operator,
a third 'generic' version was required. Dr. Ruud suggested giving
numerics multiple faces.

More recently, Larry Wall responded to the thread, adding his thoughts
and musing on whether standard Perl should include convenience operators
like idiv or if there should simply be pragmatic support for them.
A great deal of discussion followed.

Lee Duhem reported an error in a test; this was done in ticket
[perl #41158]. Jerry Gay reported that he believed the issue was
resolved in r16381 and asked Lee to check it. Lee reported that he
thought it was a bug, resolved in ticket [perl #41165].

Jonathan Worthington replied that he liked what he had read, but felt
that more information was needed on how role composition should
work. Allison replied that she was still at work on defining roles
in the objects PDD. She offered a short explanation of how it
would probably work.

Some discussion on how to implement error values also took place,
with Jonathan, Allison and Larry Wall contributing.

Steve Peters created ticket [perl #41173] to report a problem
caused by the Intel C++ compiler defining __GNUC__ although it is
not compatible with gcc. He provided a patch which attempts to address
the issue. It was applied in r16412.

Ticket [perl #41186] was created by James Keenan to report a possible
bug in ops2pm.pl. He wondered if it was intentional that a variable was
used in two different scopes. His feeling was that using the same variable
name would confuse someone.

Gabriele Renzi decided to look at problem #28 from Ovid's list of 99
problems in Perl 6. Gabriele included a solution, but wondered if there
was a better way to solve the exercise. Ovid suggested checking in the
code, if it passed tests. Gaal Yahas provided the commit bit.

Gabriele Renzi provided an answer to problem number #32 from the list of
99 problems in Perl 6 and added it to the repository. Gabriele wondered
what the expected behavior was for gcd. Steffen Schwigon had some
questions on the code, which Gabriele answered.

Gabriele Renzi inquired what the Perl 6 idiom would be for keeping code
and tests in the same file. Juerd liked the idea of a macro or a standard
subroutine, as did Gaal Yahas. Larry Wall offered an alternative using
MAIN, but noted that autocalls to MAIN are not yet implemented. He
suggested a temporary workaround.
